certain new and useful Improvements in Bottle-Closures of which the following is a specification.

This invention comprises a new form of closure for I bottles, jars or similar vessels wherein the sealing device is formed with a plurality of fingers adapted to engage a shoulder on'the outside of the bottle neck or head, and are retained in locking engagement therewith by a: retaining device permanently mounted upon the bottle and movable longitudinally thereon to lock the retaining fingers in engagement with the bottle shoulder or to release them to permit removal of the sealing device. I i I Figure 1 is a perspective'view illustrating one form of the invention withthe retaining device, that is permanently connected with the bottle, out of engagement 7 with the retaining fingers. Fig. 2 is a similar view with the retaining device embracing the seal retaining fingers. Fig. 3 is a plan of the retaining ring or device;

4, a perspective view ofone formof the sealing device; Figs. 5 and 6 are sectional views showing the positionoi the parts before and after the sealing device is pressed into. position. Fig. 7, a similar view show I which is located a sealing washer b, of cork or other appropriate material, and from the edges of which, and at an angle (at or about right angles) to the plane of which,

' extend retaining fingers c. Preferably, this plate is provided also with a flange (1 making it a cup-like structure within which the sealing disk is seated and from which the parallel retaining fingers project.

In Fig. 1, the ends of these fingers are set inwardly, as indicated at i, so that when the device is pressed over the head of a bottle, such asshown in Figs. 5 and 6, the

fingers will be expanded'somewhat and, re-acting, engage the under side of a shoulder e on the outside of the bottle head. Around the bottle, below this. shoulder, is a continuous retaining device embracing and conforming to the shape of the bottle. The diameter across its lower edge f is such as to loosely fit around the bottle and be capable oi up and down movement longitudinally of the bottle. The diameter across its upper edge 9 is greater and is such that, when this retaining device (designated by the letter h) is pushed upwardly, it embraces and clamps the retaining fingers in theirposition of engagement with the shoulder e. By slipping the ring or retaining device It downwardly out of enremoved and may readily be replaced and again locked. Figs. 5 and 6 show the retaining ring or device h as of somewhat heavier metal-than .that of which the sealling device is made. In this case, the sealing device -is oithe construction shown in Fig.4. If the ring h be held up and the sealing device'forced down until the washer seats upon the end of the bottle head, the fingers 0 will be guided or deflectedso as to pass under and engage the shoulder e on the bottle, the ring in this case acting as a die.' The final position of the parts is shown in Fig. 6. In this case, the sealing device may be re-;

moved and re-pla cedas described.

In Fig. 7 the retaining fingers are of somewhat greater length than infFigs .5 and 6 and the shoulder on the bottle is preferably concavely-curved as shown at j 4 When the ring h is held up' in the position indicated and the sealing device is forced down, the fing ers will be de-'- flected and curled inwardly'at their lower ends and closely engagethe curved shoulder of the bottle In this construction, also, the seal may readily be removed andreplaced. i The drawing shows what may properly be described as a bottle having a neck of reduced diameter which, as usual, is circular-in cross section. The invention, however, is not limited'to vessels of this particular shape nor to devices of circular' iormation. The shape of the cap. and of theretaining ring should conform to the cross section of the part ofthe vessel to which'it is applied.

, I claim as my" invention; l i i 1. The comblnatlon. with a vessel having an external shoulder around and adjacent its mouth and a seal retalnlng ring permanently mountedon the vessel below the shoulder and movable longitudinally of the vessel, of a seallng device having a plurality of fingers adapted to engage said shoulder and to. be held-in locklng engagement therewith by the ring.

2. A bottle having an annular external shoulder adjacent lts mouth, a metal ring permanently'mounted'on the' bottle below the'shoulder, its diameter ncrossits'lower edge being less, .and'lts diameter acrossits upper edge being greater, than the diameter. through the'shoulder on the bottle combined with a sealing device havlng'a plurality of retaining fingers adapted, when the device is pressed upon the bottle mouth, to pass between the ring 'and the shoulder on' the bottle and to be deflected by 'the former into engagement with the under side of the shoulder..

In testlmony whereoLl have hereunto subscribed my name.
